FILTER AND WATER-PURIFIER:

SPECIFICATION forming part of Letters Patent N0. 415,927, dated November 26, 1889.

Application filed April 11, 1889. Serial No. 306,609 (No model.)

To all -wwm t may concern:

Be it known that I, FREDERICK STILES, of 3urnet, in the county of Burnet and State of Y Texas, have invented a new and useful Improveinent in Combined Filter and Water- Puritier, of which the following is a specification.

' My invention is in the nature of a combined filter and purifier for water, designed to be placed in the bottom of the well or cistern, so as to :filter the water before it is pumped up, and also to purify the water in the well by forcing'air into the same.

It consists in the combination of the pump, a filter, and an air-pump, as will be hereinafter fully described.

Figure l is a vertical sectional elevation, and Fig. 2 is a side view.

In the drawings, A represents the cylinder .of an ordinary lift-pump, and A is that of an air-pump. These are both held in the same frame-Work B i'n parallel position, and are same there is another perforated cylinder H, about six inches in diameter and about the same length as the outer cylinder.

ln to this inner cylinder there pass the two pumptubes E and F. The tube E of the lift-pump terminates in this cylinder and opens into it, while the tube F of the air-pump passes entirely through the bottom end of the cylinder and opens into the water of lthe well or cistern below. At the points where the tubesE and F pass through the heads of the inner cylinder the joints are soldered or otherwise rendered tight. Between the inner and outer perforated cylinders there are packed vertical layers of charcoal and gravel or otherfiltering material, so that the water in the well or cistern,in passing through the outer cylinder to the interior of the inner cylinder, will be filtered by the interposed filtering material. Vhen, therefore, thelever-handle of the pump is operated, pure filtered water is drawn from the interior of the inner cylinder, and fresh air is forced down at the same timeinto the water in the well to aerate and purify it.

Having thus described my invention, what I claim as new is The combination of a Water-pump having upwardly-opening valves, an air-pump having down wardly-opening valves, and two perforated cylinders surrounding the pump-tubes and provided with a packing of filtering inaterial, the water-pump tube opening into the inner cylinder, and the pump-tube passing entirely through both heads of the sanie,suh stantiall y as and for the purpose described.
